Thiem has been the one younger guy with the game and consistency to challenge Nadal and Djokovic at slam level.
An easy slam win today would get the monkey off his back that he still hasn't won a slam, despite several finals now. And I feel that would allow him to play Nadal and Djokovic with less pressure on his shoulders in those big finals.
Losing to Zverev would be a disaster for Thiem confidence wise. He can't tell himself that he lost a slam final to two of the GOATs, and that he's getting closer to beating them.
